The LoDo and Ballpark neighborhoods have been fertile soil for breweries, so much so that at Great Divide Brewing, an entire tank farm has sprouted out of the ground, bringing with it the strong and heady aroma of steeping grain and boiling hops. But like bagels, burgers, coffee and cookies, beer smells almost as good as it tastes, making the air around the corner of 22nd and Arapahoe streets a living, breathing advertisement for delicious homemade brews.
